Answer:
see explanation
Step-by-step explanation:
The diagrams show triangular figures
The first figure has 1 dot
The second has 1 + 2 = 3 dots
The third has 3 + 3 = 6 dots
The fourth has 6 + 4 = 10 dots
Note the pattern is + 2 , + 3, + 4
Thus the fifth pattern is 10 + 5 = 15 dots
1,5,8 would be the correct answer
Answer:
3.06417777
Step-by-step explanation:
cos(40)=x/4
Distribute.
8(y+4)
8y+32= 7y+38
Subtract 32.
8y= 7y+6
Subtract 7y from both sides.
1y= 6
Divide 1 into both sides.
y=6
